MACHINE FOR HANDLILTG ROLLS OF PAPER.

Application filed July 12,

large rolls of paper although the apparatus provided by the invention may also be used in the handling of other articles. These rollsof paper come from a paper making 1 machine in a horizontal position and in the course of shipping or storing them it is necessary to upend them; that is, to set them up in an upright position. Inasmuch as these rolls are extremely heavy it is difficult to perform this operation with any of the machines or apparatus ordinarily avail abl'e,,a'nd it is the chief object of this invenily accomplished.

tion to devise a machine withwhich this handling of these rolls of paper can be read- The' various features of the'inventionwill be readily understood from the following description when read in connection with the accompanying drawings, in which:

Figure 1 is an angular view showing a machine embodying the invention in its preferred form;

Fig- 2 is an angular view showing the machine in its load receiving position; Figs. 3 and 4- are diagrammatical views showing difi'erent positions of the-mecha nism that up-ends the roll of'p'aper YFigs. 5 and 6 are diagrammatical views showing, in different positions, the'mecha- 'nism that delivers the load to the rip-ending mechanism; and.

Fig. 7 is an angular view showlng the 1 mechanism by which'the angular adjustment-ofthe trucks that support the machine is effected.

The machine shown comprises a portable frame in which theoperati'ng parts are mounted, an upending. cradle designed to receive a roll of paper in a horizontal po-.- sition and arranged tobe swung into substantially an upright position, and a trans ferring cradle which 1s arranged to receive Specification of Letters Patent.

the roll and deliver it to the upending cradle.-

Referring now to the drawings, 2 indi cates the transferring cradle, above men t oned, which consists, as clearly shown in igs. 1 and 2, of a plurality of curved arms secured together by cross pieces, the cradle pivoted to one of the base rails 4 of the machine frame. This cradle is rocked about its pivotal connection with the "frame 7 by a pneumatic mechanism which comprises an air cylinder 6, a piston rod 8 secured to the piston working in said cylinder, and a link 10 pivoted at one end to the piston rod and at its opposite end to the cradle 2. An air-valve 1 2 and suitable pipe connections enable a workman to admit compressed air to either end oi"? the cylinder 6 desired and thus to move the cradle from the position in which it is shown in Figs. 1, 2 and 5 to that in which it appears at Fig. 6, and to lower it again.

The movement of the cradle2 raises the roll of paper, which previously has been placed on it, into position to roll on to a second cradle 14. This cradle comprises a; pair of side bars 16 supporting a series of curved cross pieces 18 on which a covering of boards or other suitable material is fastened. The'shape of the cradle obviously will be made to suit the character of the load which it is designed to handle. This cradle is pivoted near one end to the rails 4, one of the pivots being indicated at 20 in Figs. 1 and 2, so that it can swing from a substantially horizontal position in' which it receives the roll of paper to a substantial upright position where it discharges the roll, setting it up on one end. The cradle 14 is supported and moved by means of a lever system which is pneumatically operated. This lever system comprises a parallelogram link system consisting of two links 21 and 22 pivoted to the rails 4, or brackets supported by them, at slightly lower points than the pivot 20, and two other links 23 and 24 also pivoted to brackets supported by the rails 4 at points below the pivotal connection of the links 21 and 22. Additional links 25 and 26 connect the links .21and 23, respectively, to the links 22 and 24,. while similar links 27 and 28 connect the upper ends of the links the entire system to collapse into a very small vertical space when the cradle is in its horizontal position, as shown in Figs. 2 and 3. V

' In order to raise and lower the cradle adjustable links 29 and .80- connect the. ends of the links and 26, respectively, to the ends of arms land 82both mounted fast on a rock shaft 34 which is supported in the upper-part of the frame. 'Another arm 86' secured fast tothe rock shaft 3% is pivoted to the forward end of a piston rod 38wh1ch is secured fast to a piston that slides'ln'a cylinder 40 which is pivoted on the frame at 42, Fig. 2. A valve 4% controls the flow of compressed a1r through sultabl'e pipe connections to the cylinder 40. When this valve is moved in a proper directionto ad- 'mlt'air to the outer end of the cylinder, it

forces the piston rod 38 inwardly and acts through theconnections just describedto ra se the cradle 14 from 1ts horizontal position, in which it is shown in Figs. 2 and 8, into a substantially upright position, as in- (llOELtBCl'lli Fig. 1. A reversal of theair supply to the cylinder lowers the-cradle again. 111g. 4 shows. the-cradle 1n an intermedlate position. The free or swinging end of the cylinder 40 is partly counterbalanced by a weight 46 which is connected to the cylinder by a rope 48. a It will now be understood that in'using the machine the roll R of paper is {run on to the cradl'e'2 while it is in-the position in .which it is shown in Figs. 1, 2, and 5. The I 'fworkman then moves the valve 12 in the "of the cylinder 6,-which acts through the proper direction to admit air to the rear end connections with the cradle 2 to raise the cradle into the position n which it'is shown in Fig.6, where the roll of paperwhich it previously held is transferred to the cradle 14-. The workman next operates the valve M to admit air to the forward end i of the upp'er cylinder 10 and thus causes the connections between this cylinder anl" the cradle 14 to raise the cradle and cause it to upend the roll. The'valves 12 and44 are then reversed toreturn the cradles 2 andi'lt to their original positions. The machine thus accomplishes very quickly an operation which heretofore has been very slow and arduous. V 1

Struts 50 preferably are secured to each of the rails 4 to prevent their buckling under theload. These struts are each provided with a pivoted endi'51 which may be swung up into an inoperative position when it is desired to move the machine.

As shown 1n the drawings, the frame is supported on trucks 52' and, in order to" facilitate the movement of'the machine in predetermined direction,'a' cable or chain" 54: is fastened to a small roll mounted on- :the' shank of each truck and a' hand lever 56. is connected to this cable to enable the workman to adjust all the trucks. simultaneously into any desired angular position.

. The cable 5a is run over idlers or-guide rolls 58, aseindicated in Fig. 7, to keep it out of the path of movement of the cradle 1s.

The invention has been herein illustrated embodiedin a portable'machine. It is obvious that under some circumstances the might be desirable to omit the transferring cradle and locate the-upendln cradle and the operating mechanism therefor in'a pit.

It is obvious that the specific design in which the invention is embodied and the details. of construction will be varied to suit therequirements of individual cases and that the specific form shown may be modified considerably within the skill-of the mechanic and the discretion of the designer i'vithout'depaiting fromthe spirit or scope of theinvention.

a fluid pressure mechanism, and pivoted connections between said leverv system and said fluid pressure mechanism enabling said fluid pressure mechanism to move said cradle from one of said positions to the other.

7. A machine for handling large rolls of paper comprising, in combination, an upending cradle mounted to swing from substantially a horizontal load-receiving position to a substantially upright load-dis charging position, mechanism for operating said cradle, comprising links moving on stationary pivots and extending substantially parallel to said cradle, said links be ing arranged to collapse below the level of the cradle when it is in horizontal position, and power operated means acting through said links to move said cradle from one of said positions to the other.

In testimony whereof we have signed our names to this specification.
